... A novel device has been designed and successfully used to produce, and accurately place, individual droplets of pesticidal formulations onto target surfaces. The device is based on the technology of impulse jet “drop on demand” printers, and can produce a single droplet when required, or can run...

... spray clouds of toxic materials; yet it can also be used as a highly refined tool for fundamental studies on single droplets. The ability to simultaneously measure droplet size and velocity is a particular advantage of the system. As with any measuring technique it is necessary to accept...
